Prayer Drain Calculator

INSTRUCTIONS

To find out how much prayer points a certain combination of prayers will drain every second, first enter the amount of prayer bonus your equipment gives, and then select the prayers you wish to use. Use the drop-down list to switch between regular prayers and ancient curses.

To find out how long you can maintain the use of the selected prayers, enter your prayer level, select the type of prayer-restoring potion you will be using, and then enter how many potions you will bring.

NOTES

Use our equipment builder if you need help figuring out how much prayer bonus a certain equipment setup gives.

If the calculations appear to be off, keep in mind that numbers are rounded before they are displayed. For example, a drain rate of 3.333 repeating will be displayed as 3.3 by the calculator. Behind the scenes, the calculations are performed using unrounded numbers.
